Does average running position matter on super speedways?
Not really.
That's a chart of average running position against average finish of all driver seasons since 2020, minimum four starts. The point at the bottom is Denny Hamlin's 2020, where he had an AFP of 2.25.

I was curious after writing up the Talladega preview. This dataset is full-race ARPs. Next to look at would be whether running position gets more predictive later in the race on supers. That'd allow looking on the relationship on a race-by-race basis.
